When using preg_match, why #^(([a-z]{2})/)?(([a-z\-]{3,})/(([a-z\-]{3,}))?)?$#i
match ab/cde/fgh
and do not match ab/cde
?
I mean:
preg_match_all('#^(([a-z]{2})/)?(([a-z\-]{3,})/(([a-z\-]{3,}))?)?$#i','ab/cde/fgh',$match)
$match = Array
(
[0] => ab/cde/fgd
[1] => ab/
[2] => ab
[3] => cde/fgd
[4] => cde
[5] => fgd
[6] => fgd
)
and
preg_match_all('#^(([a-z]{2})/)?(([a-z\-]{3,})/(([a-z\-]{3,}))?)?$#i','ab/cde',$match)
$match = Array ()
Because as the regex is written, you need a slash after the cde
. ab/cde/
should match.
